Title: "Collisional operators"

Lecturer: Dr. Florin Spineanu

Work Sessions of Plasma Theory, Fifth meeting

Abstract: The exchange of momentum and energy in plasma is mediated by collisions. The balance of forces, which establishes a cuasi-equilibrium of flows and loss fluxes is governed by collisions. In the kinetic approach the details of collisional exchanges of momentum are complex and take into account the distinctive types of neoclassical orbits (trapped or circulating). We will examine the collisional processes first on general grounds then in a series of applications. This should help us understand not only the role of collisions but the way we must choose to place emphasis on certain particularities, i.e. to adapt the operators to various regimes.
This should prepare us for the review of the connections between friction forces and transport fluxes.
